’Tis the season . . . to pick the winners and losers of New York politics for 2013. And this year, more than most, saw as many winners as there were losers, although once again, average state residents were the biggest losers of all.

State government ends the year with virtually nothing accomplished in the way of genuine reform to make the state more affordable for its residents, more attractive to job-creating businesses and more likely to attract to public service individuals of courage and integrity.

And, despite Gov. Cuomo’s claim as the year got under way that lawmakers had undergone a positive transformation, the scandal-plagued Legislature didn’t disappoint, with another round of stunning indictments — compliments of one of the year’s biggest winners, US Attorney Preet Bharara, a huge new political star.

Bill de Blasio was, of course, a major winner. The little-noticed public advocate and former Cuomo employee at HUD pulled ahead of the mayoral pack with a leftist class-warfare message and will soon be one of the most important “progressive leaders’’ in America. As the new mayor, he will be in a strong position to challenge and politically damage Cuomo, and the governor is clearly concerned.

Assembly Speaker Sheldon Silver was another big winner, remaining strongly in control of his powerful position, despite a total of three sex scandals (Michael Boxley 1 & 2 plus Vito Lopez) and the arrest of his chief of staff’s husband in a massive scandal that severely damaged one of the city’s best-known charities.

Other winners include Westchester County Executive Rob Astorino, a Republican who won a landslide re-election victory in a heavily Democratic county and emerged as the GOP’s front-running candidate for governor next year, and Syracuse Mayor Stephanie Miner, who, despite being Cuomo’s handpicked co-chair of the state Democratic Party, had the courage to challenge the governor on the fiscal disasters facing local governments across New York.

Gov. Cuomo, after two strong years as a fiscal moderate and social liberal, emerged as the biggest loser of the year, spending much of 2013 pursuing the “progressive’’ programs he had once forsworn.

These included higher taxes on the wealthy, a “women’s agenda’’ that addressed supposed concerns that were already covered by law, a ban on legally possessed semiautomatic assault weapons that are rarely used in crimes and other restrictions on gun ownership, plus a $350-a-family vote-buying scheme that Boss Tweed would have considered shameless.

Cuomo a year ago said a final decision on fracking for natural gas — which could create 25,000 private-sector jobs — was just weeks away. If an illustration of the word “dithering’’ were ever needed, his failure to make that decision would provide one.

Cuomo’s unfocused Moreland Act Commission investigation of the Legislature has produced such bitterness that his future ability to work collegially with lawmakers is in doubt.

Other losers this year include Lt. Gov. Robert Duffy, who will likely be dumped from the ticket next year.

Then there’s Republican Senate leader Dean Skelos, who caved in to threats from Cuomo and signed a “message of necessity’’ that jammed the anti-gun SAFE Act through the Legislature without debate, thereby dividing the GOP into upstate and downstate factions.

There’s also the inexplicably meek Assembly GOP Minority Leader Brian Kolb, who, with Silver engulfed in scandal, has yet to utter a single word critical of his supposed foe.

Other losers include Sens. John Sampson and Malcolm Smith, both former Senate majority leaders, and Assemblyman Eric Stevenson, all indicted on federal corruption charges,.

Finally, of course, there is former Assemblyman and Brooklyn Democratic Chairman Vito Lopez, who lost a bid for City Council after resigning in disgrace amid sexual-harassment allegations.
